Dear Marge,
In Sacramento, CA, Arum italicum is also an invasive weed, at
least in my yard. This spring I have resorted to digging the tubers. The
fact that so many are very small makes me believe I can nearly eradicate
them. I do want a couple of accent plants for they are handsome striking
plants with scarlet berries in the fall.
Sincerely, Joyce Miller, Sacramento, CA Zone 9A.
